Let's put this in perspective;
You have a machine made bottle produced in 1980. A production facility could make thousands of these bottles in minutes.
In your ebay listing, you provide a link to this bottle at the Corning Museum. It is fairly clear from browsing the Corning database that they have many items in their holdings which are representative of a manufacturer or era or mold technique and are not necessarily in the collection because they are rare and valuable.
You have a lot more research to complete to convince people that this bottle is "super rare" and valuable, as you suggest in your ebay auction.
